HOUSTON --Astronaut Tim Kopra is recovering after being hurt in a bicycle accident. Details of the accident have not been released, but we're told the 47-year-old had minor injuries. Kopra, who was the first member of the International Space Station to Tweet in space, was scheduled as the lead spacewalker for next month's shuttle Discovery launch, but his injury could delay the final mission for Discovery.
That was scheduled for February 24. If so, it would be the latest in a series of setbacks for the mission.
